Application filed November 16, i888- Sorial No. 291,025. (No modeLl Y.To coli whom it Hwy-concern:

Be it known that l, MILO DJBEACH, a citizen of the United States,residing at .Litchield, in the county of Litchfield and State otConnecticut, have invented cert-ain new and useful Improvements inHillside-Flows; and I do decla-rc the followingro he a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use tliesarne, referencebeing had to the accompanying drawings-and to the letters and figures ofref-.

one side. and decreased when it stands on the other side. These resultsare accomplishedv by the mechanism shown inthe drawings, in Which-Figure l is a sideelevation of an iron-beam plowr embodying myimprovements. Fig, 2 is a Vertical longitudinalv section of the worningparts. Fig. 3 is a horizontal sectionthrough the shaft. Figtis aVertical oross-section through the handles and the duplex hook. Fig. 5is a View of the double eccentric for' shifting the jointer. Fig. 6shows a-modied form of the same for shitting the colter.

Figs. 7, 8, and 9 illustrate the duplex hook. Fig. 10 is a cross-sectionof the tubular bean ing and the colter, taken on line :l: zg, Fig: li.Fig. 11 shows the scctoigear. Fig. l2 is a crosssection of the jointeron line y y, Fig. 2. Fig. 13 is a plan of the crank-head. Fig. 14 is aView of the colter; and Fig. l5 is a crosssection of the beam on line ee, Fig. l(

The same letters refer to the. same parts in all the igures.

the standard at c, and also to a cross-har, D, which is fastened by aholt, d, to a lug or ear, a,

projecting rearwardly i'rointlie standard. Between the handles ispivoted the duplex hook E, which is composed of a huh, e, having twoarms, e', meeting the hub at an obtuse angle. On the outer end of eacharm is an upwardlyturned hook, e2, having its upper edge down- Wardly'inclined toward the rear, as shown in Fig. S. Along the upper .side ofeach arm runs a rounded rib, e3. From theupper face foi the hub projectone ormore studs, et, which enter corresponding holes in the end of aheaded sleeve, F, and thus look the hook and sleevelogether. Other meansof accomplishf ingthi's will be'readily suggested. The sleeveiscylindrical and fits into a bearing formed in the cross-har D. Theupper end of the sleeve is fiattened on opposite sides to enter anoblong slot, g, cut in the plate G, which rests on the upper face of thecross-bar D. Through the huh e and the sleeve-Fv passesa bolt, H, whichhas a broad flat head, h, bearing Aagainst the under side of the hook E.The opening in the hub e is larger than the bolt, so that the huh isloose on thebolt, which eX- tends considerably' above vthe plate G, andcarries a cap, 7L', which may be integral'with the nut h2, or separatefrom it, as desiredr- Between the cap and the pla-te G is seated ahelical spring, H', encircling the bolt., which is thus free to slideaxially in the sleeveF, but is normallyheldwith its headholding the hookE in place against the sleeve. The hook can, however,.he sprung slightlyaway fronti 'thesleeva so that when swung ffroni an opposite position tothe other it may ride under one of the small liigs d', which depend-fromthe under side of the cross-bar Dfan'd serre to loek the hook in place.The lugs ld and the ribs ea are rounded, as shown in Fig-7, so

as to readily be engaged or disengaged by the application of sufficientforce.V

On each under side of the mold-board is a catch or lugo, having one facebeveled, as shown in Fig. 4. The edgeof the lug is also inclined, tocorrespond with the edge ot' the hook e2, as shown in Fig, 8. WV hen theplow is to be reversed, the plowinan pushes the projecting arm of thedouble hook E. with his foot, which disengages said hook from the' lug bon the mold-board and from the lug d on the crossbar and throws itaround into its other position, whereit is locked hy the lug the hook tohave sufficient play to act in this' manner, and the inclined edges ofthe hook e'2 and the lug b have a tendency on meeting to throw the arm'eforward and so avoid any danger of disengaging it from the lug d.

\Vhen the duplex hook is swung frein one I side to the other, itoscillates the sleeve F and the plate G. The front edge of sai pl'ate'isa segment ot' a circle struck from t ecenter of the sleeve F, and is cutinto bevel gearteeth g'. These mesh with. a sector gear wheel, I', on ashaft, I, which is stepped in a bearing, d?, preferably formed in thecrossbar D, and extends upward along'the back of the standard, as shown,its upper end be ing received in a semi-cylindrical socket, j, formed atone end of a double eccentric, J. rIhe shaft I is secured in the socketby a bolt, as shown. socket allows the shaft I1 to be stepped in thebearing d?, andrthen dropped laterally into the socket and fastened. Atthe end of the double eccentric ,J is formed. .a cup-shaped hub, 7",cylindrical on the outside. The axis of this hub is in line with theaxis of the socket j and the shaft I, so that the hub revolvesconcentrically with the shaft I.

The double eccentricJ consists of a cylindrical shaft united tol thesooketgl at one end and to the hub j at t-he other, but so placed withits ends on opposited sides of the axis of the shaft'I and hub 7"V thatthe axis of the eccentric J crosses the axis of the shaft I and hub jpreferably about midway of the eccentric J. 'hen the shaftl is rotated,the ends of the eccentric .I will'describe small circles around the axisof the shaft. The hub j -is held in a cylindrical bearingformed in ahorn, A', which may be castA integral with the beam A, or may beattached to it.l

The jointer is provided with a, stem, K, fit- 5o ting in a tubularbearing, A2, formed in the beam A'. A transversebol't, a', engages withsys -a groove, 1c, cut partially around thestem K, and prevents anyendwise motion of said stem in its bearing. In the upper end of thestern is a diametrical slot, k', whose width is slightly greater than4the diameter of the double eccentric J, which'is engaged with the slot,as v,shown in Figs. 2 and A3. The axial lines of the shaft I, theeccentric J, and the jointer-steui K all intersect at the point X, Fig.l3.

Upon revolvin g the shaft I the vibration of the double-eccentric causesthe stem K to oscillate in its bearing, the angular movement being twicethe angle between the axes of the shaft I and-the eccentric.

To the lower end of the jointer-stem is at- The semi cylindrical form ofthey tac-lied the jointer, composed of a Socke-ted head, K', providedwith a setscrew,-\1', engaging with suitable depressions in the stem Kfor the purpose of adjusting the jointer up and down on the stein. Tothehead K are cureda suitable point andilaring wings or mold-boards, asshown, wherebyT the jointer is4 en( bled to lslice off the turf inadvance of the plowshare whichever way the furrow is being turned. Asingle mold-board joiuter may be used, if desired. 'hen the duplexY hookEis thrown from one side to the other, the sectorgears will beopcrated,and they are so pro- .I portioned that the shaftl lis therebygiven a half-revolution. This is sufficient to throw the point of thejoint-er over to the side opposite to the mold-board of the plow in aposition to properly cut the turf.

In order to automatically swing the elevis to properly adj ust the draftof the plow, a shaft, L, is mounted in a tubular bearing, A, cored outin the plow-beam. The rear end of this shaft projects into thecup-'shaped hub j', where a slot, l, in the shaft engages with a pin,f2, passing diametrically across the hub. The slot and bolt constitute auniversal joint, by which the motion of the sha-ft l is communicated tothe shaft L.. i

- In the forward end'of the shaft L is a slot, l', which engages with apin, m,diametrically crossing a cavity in the end of the-shorthorizontal 'shaft M, mounted in a tubular bearing,

Af?, cored out in the beam A. The shaft M projects out from the end'vofthe plow-beam and carries a flat head, M', the front edge of which is acurve. In each side ofthe head is cut a groove, m', concentric withandparallel to the curred edge, leaving a flange, m2, on each side of'the head. A dog, 'Nhaving a T shaped slot fitting the flange and thegrooves, is adjustable along the head by means of the set-screw Freinthe front of the dog projects a cylindricalA nose, N.

The clevis O is Ushaped,'and is pivoted to swing horizontally by' meansof the bolts P, which are provided with suitable nuts, p, lreceived inslots in the web of the beam A. The

curve of the head M' is struck from theaXis' of the bolts P-as acen-ter.l In theinner face of the clevis, which has the samecurvature as.the head M', is a groove, o, which engages with the nose N of the dogN.

Then the nose N lies in Ithe axis of the shaft M, it will have noeffect' upon the clevis when the shaft is rot-ated; but if the dog isadjusted to one side or the other along the head lVlQthcn whenl theshaft is`rotated the nose N acts as a crank-pin and throws the clevis toneside or the other, and to an .extent correspondingavith the distanceof the nose from the axis of the sha-ft M. In this way the angle of theclcvis to the line of draft can be regulated with great nicety, and iscertain to give exactly the same amount of side draft in both positionsof the plowshare and mold-board. rlhe clevis is automatically shifted atthe same time with the jointer and IOO IIO

scacco bythe single operation of throwing the duplex hook from one sideto the other. Under some circumstances, however, it may be desirable ornecessary to give more side draft when running the plow in onedi-rection than when running it in the opposite direction. To accomplishthis, the @levis-hook Q is attached to the clevis O by a bolt, q,passing loosely through one of the holes o in the head of the clevis,and thev sides of the clevishead, are chamfered ott toward the iront andrea-r from aline just back of the bolt-holes, as shown in Fig. 3. Thisconstruction permits the clevis-hook to be laterally vibrated, and it islocked in any desired relation to the clevis by means of intermeshingteeth or corrugat-ions o2 q', formed, respectively, on the front edge otthe clevis and the inner face of the slot in the clevis-hook. vTheseteetlirun verpartial revolution on lits axis.

tically the entire length ot the surfaces in which they are formed. Toadjust the hook Q, the bolt q is removed, the hook is pulled slightlyaway from the clevis, moved laterally the required amount, and thenpushed baekto engage its teeth q with the teeth o2 of the clevis andbring the bolt-holes into line, so'thatbolt q may be replaced. Thisadjustment oi the clevis-hook will increase the side draft when theclevis stands on one side and reduce it when the clevis is reversed. Theside drait can therefore be regulated with great exactness to suit thevarying conditions under which the plow is used. A colter may besubstituted for the jointer, if desired. lt is shown in the dotted'line'sin' Figs. l and 2 'and in full lines in Fig. 14. Fig.. 6 showsthe eccentric for shitting the colter, and Fig. ll is a cross-section ofthe colter where Vit enters the tubular bearing A2. The stem R of thecolter tapers oft toward the top, so as to be able to vibrate sidewisein the bearing. In front ci the tubular bearing A?r is formed a recesso2to receive the upper part of the dat blade Rf of the colter. The..eccentric J', which shifts the colteigis single instead of double, andhas a greater throw at its rear end than in front, as indicated by thepositions of its axial line relative tothe axial line of rotation. Adouble motion is thus imparted to the'colter-one ot vibration laterallyin the bearing and one of The vibratory motion throws the point of thecolter into line with the plow-point. The rotator-y movement brings upthe edge of the colter in to a nearly vertical plane, andtherebycounteracts the tendency or" the vibratory motion to tilt the colter outof an upright position. The point of the colter lies in the axis ofrevolution of the stem R, and is therefore not affect-ed 'by therotatory motion. l

lt will be noticed that the eccentrico .l and i J and theadjustablecrank-pin N are so disposed as to be onradeadfcenter whenV the jointeror colter and the clevis occupy their working positions,- so 'that theeccentrics and the pin are in the best position to resist strains,

l and are relieved. from all danger of being thrown out.; of theirpositions by the stems of the j ointer or colter and the head of theclevis.
